tesa® 64912

Double-sided PE foam tape



Product description

Primer process is annoying but essential for many suppliers in the Automotive Industries nowadays!
The introduction of tesa® 64912 can help our customers eliminate the primer in the process1!

tesa® 64912 is a double-sided PE-foam tape. Its high performance adhesive enables primerless bonding of Low Surface Energy (LSE) and Medium Surface Energy (MSE) substrates.

Features:
  • High initial performance to LSE and MSE surfaces without primer
  • Reach ultimate peel adhesion level right after application
  • Superior peel adhesion on PP substrates, even at an application temperature down to 5 °C
  • Reliable performance at higher temperature
  • Highly conformable and gap filling
  • Excellent converting properties


Benefits:
  • Eliminate the primer in the production process
  • Enable a much more efficient and robust application
  • Skip the pre-heating of tape in winter time
  • Realize a healthier working condition
  • Reach a more environmental friendly production

(*) For glass and soft EPDM substrates primer is still needed.

Main applications

Developed for permanent mounting of similar and / or dissimilar plastic parts, tesa® 64912 can be widely used for mounting applications of smaller parts. Such as permanent mounting of
  • park distance sensor bracket
  • entry trim
  • interior decorative trim
